why

Skill2 starsChanged 29 days agoMITView on GitHub

Read-only research into historical code design decisions: why a subsystem works this way or why a particular approach was chosen. Uses relevant Git history and available supporting sources, separating documented facts from inference. Use how for runtime behavior; do not select for implementation or debugging requests.

Why

Investigate the forces that shaped code. Read epistemics and separate direct evidence, supported conclusions, inference, speculation, and unknowns.

  1. Anchor files and symbols with blame, history through renames, substantive commits, and relevant PR discussion.
  2. Map available sources to categories. Search only the relevant workspace/topic/time window. Start with Git and available PR history, then relevant tickets, docs, chat, observability, errors, or analytics. Do not assume gh auth or every connector exists.
  3. Broad independent sources can be delegated using the native contract and investigator prompt. Give each the relevant category playbook; defensive code may need incident-postmortem. Narrow questions run directly.
  4. Reconcile with the synthesizer prompt. Spot-check citations, keep contradictions, and report unavailable/unsearched categories.

Return documented facts, inferences, competing hypotheses when useful, gaps, and actual sources. Before a change derive Preserve / Change / Avoid / Risk constraints. Research does not authorize contacting people or editing records.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
